.CUUPLING FOM CNNECTIG PlllPES AND FAUCJETS T0 RECEPTACLES.

ToaZZ whom f may concern:

Beit know that li, WALTER M. Sr. ELMo, a citizen of the United States. and a resident of San Juan, Porto Rico, have invented a new and Improved Coupling for Connect-y ing Pipes and Faucets to Receptacles, of which the following is a full, clear, andeX- act description. v

My invention has for itsobject to provide a couplin havin means iter penetrating areceptac e and or connecting apip'e therewith around the opening made in the receptacle.

rlhe coupling is constructed with a hollow ,shank having a point at its end for penetrating the receptacle, there being a plurality of levers fulcrumed around the shank, arms of which close vthe openings in the sides of the shank when the shank is pushed through the opening in the receptacle,.the other arms of the levers being adapted to be engaged by a nut meshing with a thread on the shank for holding the rst Vmentioned arms of the levers against the inner side of the receptacle while the nut having a gasket, is turned home against the outer side of the receptacle.v

Additional objects of the invention will appear in the following s ecication in which the preferred form o my invention is disclosed. .A

lln the drawings similar reference characters refer to similar parts in all'the views in which v Figure 1 is a side elevation of my invention; Fig. 2 is a view similar to that shown in Fig. 1, but in section and illustrating the manner in which the coupling is secured to the receptacle; Fig.. '3 is a sectional view on the line 3 3 of h`1g. 2; and'lFi t is al sectional view on4 the l1ne t-ll ot ig. 3.

By referring to the drawings it will be seen that a hollow shank 5 is provided, to one end of whicha faucet e may he secured. The other end ot the -hollowshank 5 has a point 't' for penetrating a receptacle 8. ln Fig. 2 of t e drawings, an opening1 9 4is shown, which has been made bythe pointed v end 7 of the shank. At the sides of the rat shank 5 there are lugs 10 to which are tulcrumed at 11, bell crank levers 12, these bell crank levers 12 having arms 13 which are adapted to close the openings 1.4 in the'sides ot the shank 5,adjacen`t the ointed end i? when thearnis 1B are dispose parallel with the side et the shank 5 as illustrated in Fig.

1 'of the drawings. When the arms 13 of i the bell crank levers 12 are disposed in this position, the pointed end 7 of the shank 5 is forced through the receptacle 8, forming the opening 9, the arms 13 of the bell crank levers 12 being disposed within the receptacle. The other set of arms 15 of the bell crank levers 12 are moved from the position shown by the full lines in lFig. 1 of the drawings to the position shown in Fig. 2 ofthe drawings, when the arms 13 willbe disposed against the inner side of the receptacle 8. rlhe nut 16 which'meshes with the outer thread 17 on the shank 5 is then turned lrelatively to the shank for receivingv the arms 15 of the bell crank levers in the annular opening 18 in the nut 16. This serves to hold' the bell crank levers 12 in the position indicated in Fig. 2 of the drawings while the nut 16 is turned home against the outer side of the receptacle 8. llt will be noticed Athat there is an annular recess 19v 'in the nut 16' for receiving a gasket 20,

pivoted at the outside ot the shank and disposed therearound, one set of arms of the bell crank levers being adapted to be disposed against the shank and within the plane at the sides of the base, and a memlwr disposed around the shank for movement longitudinally thereof, the inner sides et the member diverging in the general dirmihon of the bell crank levers and being adapted to engage one set of arms of the bell crank levers for pressing them against the hollow shank tor the purpose specied.

2. lin a coupling of the class described, a i

hollow shank pointed at one end with an Aopening through the side of the shank adjacent the said end, a pluralit et bell crank leverspivoted at the outer si e ci? the shank and disposed therearound, and a member disposed around the shank for moving len@ gitudinall thereof, the inner sides et the member verging inthe general direetien y of the bell crank levers and being adapted to engage one set of arms of the bell crank levers for pressing 4them against the hollow shank, there beingan annular recess in the outer face of the member, and a gasket in the annular recess for engaging the side of a receptacle around an opening made by the pointed end ofthe shank.

3. In a coupling of the class described, a hollow shank pointed at one end with an opening through one side of the shank adjacent the said end, a plurality of bell crank levers fulcrumed outside of and around the shank, and a member disposed around the shank for'yengaging one set of arms of the bell crank levers and for pressing against one side of a receptacle, and with the other set of arms of the bell crank levers in engagement with the other side of the receptacle.

4. In a coupling ofthe class described, a

hollow shank havlngat one end a point the` base of which is greater in diameter than the'shank,a plurality of bell crank levers disposed at the outer side of the shank and pivoted thereto, one set of arms of the bell crank levers beingadapted to be disposed against the shank and within the planes of the sides of the base and a member on the shank for engagin the other set of arms of the levers for ho ding them adjacent the.

shank.

5. In aeouplin of the class described, a hollow shank having an outer thread, there being an opening through the side of the shank, a lever `fulcrumed to the sideof the shank and .having an arm adapted to close the opening and to move to a position at an angle to the shank for engaging the inner the thread on the shank and havin side of a receptacle, and a nut meshing with an opening for receiving the other arm o the lever when the nut is turned home against the outer side of the receptacle.

6. In a coupling of the class described, a hollow shank, there being an opening through the side of the shank, a lever fulcrumed to the side of the shank and having an arm adapted to close the opening and to move to a position at an angle to the shank for engaging the inner side of a receptacle, and a member disposed around the shank and having an opening for receiving the other arm of the-lever when the member is pressed against the outer side of the receptacle.

7. In a coupling of the class described, a hollow shank with an opening through the side thereof, a lever ulcrumed to the side of the shank andl adapted to close the opening, and

means for holding the lever against the inner side of a receptacle when the shank is disposed in an opening in the receptacle.

8. 'In a coupling of the class described, a hollow shankwith an opening through the side thereof, a lever fulcrumed to the side of the shank andadapted to close the opening, and means for moving the lever away from the opening when the shank is disposed in an opening in a receptacle.

In testimony whereof I have signed my name to this specification in the presence of the two subscribing witnesses.
